Underwater target image collection device

Abstract

The invention discloses an underwater target image collection device. The device comprises a close box and an underwater motion robot. A camera is mounted in the close box. A transparent collection window is arranged at the part of the box corresponding to the lens of the camera. The underwater motion robot is fixedly connected with the close box. The underwater motion robot is responsible for moving the close box to a suitable target location. According to the device, through addition of the close box, the working distance of the camera is increased, the visible range of a target in a muddy water environment is effectively improved, the size of an collected image is relatively large, the close box is pushed to be close to the target by the underwater motion robot, and therefore, the definition of the collected image is high.

Description

technical field [0001] The invention relates to an image acquisition device, in particular to an underwater target image acquisition device. Background technique [0002] In the past ten years, underwater structures have developed vigorously, and a large number of wading bridges, underwater tunnels, and ocean platforms have been built. These underwater buildings are affected by factors such as natural aging, water erosion, corrosion, and impact damage of water-carrying objects during use, resulting in varying degrees of safety problems. Therefore, it is necessary to carry out regular inspection, evaluation and maintenance of underwater targets. This work is usually done by professional divers, but the underwater conditions of various water bodies are complex and changeable, which seriously affects the work efficiency of divers and has personal safety problems. People consume a lot of energy underwater, and it is difficult to guarantee the necessary working hours. The limit...

Problems solved by technology

When the robot is in the water, it is easily affected by the current, and it is difficult to accurately keep the working surface without displacement. When the propeller is close to the river bank, the bottom of the water, etc., it is easy to bring up sediment and make the water more turbid.

Although the camera adopts waterproof and anti-pressure treatment, the effective shooting distance is short in the turbid water, and the image definition is not high. It is difficult to meet the image size and accuracy required by the inspection, and the workload required to complete the inspection is relatively large.

Generally, when collecting images of underwater targets, the light from the light source is incident on the target surface, and then reflected from the target surface to the camera to complete the image acquisition. reduce

If in order to ensure a clear image, the distance between the incident light and the reflected light must be reduced, which will lead to a reduction in the camera's collection range and an increase in the workload of completing the entire target collection.
